Interpretation of results:
GHS criteria not met
Conclusions:
(i) The test substance does not sustain a flame
(ii) The test substance is not classified as highly flammable in terms of its burning characteristics.
Executive summary:

A test was carried out in accordance with EC Method A.10 and in compliance with GLP.

i) The test substance does not sustain a flame

(ii) The test substance is not classified as highly flammable in terms of its burning characteristics.

Description of key information

Negative test results were obtained in flammability studies as the substance did not propagate combustion, the substance is not classified as highly flammable in terms of its burning characteristics, Schürch 1992.

As the substance is known to be stable in contact with air at room temperature for prolonged periods of time and is soluble in water to form a stable mixture no studies are needed with respect to “pyrophoric solid features” and “Substance/ mixtures with in contact with water emits flammable gases”, respectively.  Also no study is needed to determine self-heating characteristics because the substance is completely molten at 160 °C and there is no evidence of self-heating properties for this substance up to 400 °C. ).

Key value for chemical safety assessment

Flammability:
not classified

Additional information

Justification for classification or non-classification

Based on the available information, the test substance is not classified as flammable solid, self heating substance, pyrophoric solid or substance which in contact with water emits flammable gases in accordance with EU Classification, Labelling and Packaging of Substances and Mixtures (CLP) Regulation No. (EC) 1272/2008.
